I don't know how California works but here in Illinois when my Parents got divorced there was no two sides about the order of protection in the beginning; all my mother had to do was say she felt threatened even though my father had never been abusive and she got the temporary order. Thankfully for my dad he fought back in court during the hearing for the permanent order of protection and it was not granted.

The point is we already have a system to deal with firearms rights during a divorce when someone feels threatened; we don't need more laws mucking it up.
